Currently, the macros only work with fairly recent gcc versions, but there
is room to expand them to other compilers that have comparable features.
Heavily revised and autoconfiscated version of a patch by Andres Freund.
Python can be built to have two separate include directories: one for
platform-independent files and one for platform-specific files. So
far, this has apparently never mattered for a PL/Python build. But
with the new multi-arch Python packages in Debian and Ubuntu, this is
becoming the standard configuration on these platforms, so we must
check these directories separately to be able to build there.
Also add a bit of reporting in configure to be able to see better what
is going on with this.
There was a hack put into install-sh to call strip with the correct
options on Mac OS X. But that never worked, because configure
disabled stripping on that platform altogether. So remove that dead
code, and while we're at it, update install-sh to the latest upstream
source (from Automake).
Instead, set up the right strip options in programs.m4, so this now
actually works the way it was originally intended.
The BSD-ish members of the buildfarm all seem to think removing this
was a bad idea. It looks to me like it resulted in omitting the system
header inclusion necessary to detect the fields of struct tm correctly.
ENABLE_DTRACE unused as of a7b7b07af3
HAVE_ERR_SET_MARK unused as of 4ed4b6c54e
HAVE_FCVT unused as of 4553e1d80f
HAVE_STRUCT_SOCKADDR_UN unused as of b4cea00a1f
HAVE_SYSCONF unused as of f83356c7f5
TM_IN_SYS_TIME never used, obsolescent per Autoconf documentation
PGAC_PATH_COLLATEINDEX supposed that it could use AC_PATH_PROGS to search
for collateindex.pl, but that macro will only accept files that are marked
executable, and at least some DocBook installations don't mark the script
executable (a case the docs Makefile was already prepared for). Accept the
script if it's present and readable in $DOCBOOKSTYLE/bin, and otherwise
search the PATH as before.
Having fixed that up, we don't need the fallback case that was in the docs
Makefile, and instead can throw an understandable error if configure didn't
find the script. Per recent trouble report from John Lumby.
Original patch by Lars Kanis, reviewed by Nishiyama Tomoaki and tweaked some by me.
This compiler, or at least the latest version of it, is currently broken, and
only passes the regression tests if built with -O0.
Because of ABI tagging, the library version number might no longer be
exactly the Python version number, so do extra lookups. This affects
installations without a shared library, such as ActiveState's
installer.
Also update the way to detect the location of the 'config' directory,
which can also be versioned.

This is reported to be necessary on some versions of that OS. In service
of this, cause PGAC_PROG_CC_CFLAGS_OPT to reject switches that result in
compiler warnings, since on yet other versions of that OS, the switch does
nothing except provoke a warning.
Report and patch by Ibrar Ahmed, further tweaking by me.
When testing the stderr produced by various thread-support flags, also
run a compilation in addition to a link, because clang warns on
certain flags when compiling but not when linking.
This adds collation support for columns and domains, a COLLATE clause
to override it per expression, and B-tree index support.

This can be used to build 64 bit Windows binaries, not only on 64 bit
Windows but on supported cross-compiling hosts including 32 bit Windows,
Cygwin, Darwin and Linux.
build tree. If we actually build the docs in the VPATH tree, those dirs
will get created then; but if they're present and empty, they capture the
vpathsearch searches in "make install", preventing installation of prebuilt
docs that might exist in the source tree. Per bug #5595 from Dmtiriy Igrishin.
Fix based on idea from Peter Eisentraut.
This variable is apparently only for Python internally. In newer releases
of Python this variable pulls in more and more libraries that users are
less likely to have, leading to potential build failures.
compilers, by applying a configure check to see if the compiler will accept
an unreferenced "static inline foo ..." function without warnings. It is
believed that such warnings are the only reason not to declare inlined
functions in headers, if the compiler understands "inline" at all.

versions < 5.8. Also, if there's no Perl, emit a warning informing the
user that he won't be able to build from a CVS pull. This is exactly the
same treatment we give Bison and Perl, and for the same reasons.
Behaves more or less unchanged compared to Python 2, but the new language
variant is called plpython3u. Documentation describing the naming scheme
is included.
shell construct to hide away the stderr output. Python 3.1 actually core
dumps on the current invocation (http://bugs.python.org/issue7111), but the
new version also has the more general advantage of saving the error message
in config.log for analysis.
perl_embed_ldflags setting. On OS X it seems that ExtUtils::Embed is
trying to force a universal binary to be built, but you need to specify
that a lot further upstream if you want Postgres built that way; the only
result of including -arch in perl_embed_ldflags is some warnings at the
plperl.so link step. Per my complaint and Jan Otto's suggestion.
Update install-sh to that from Autoconf 2.63, plus our Darwin-specific
changes (which I simplified a bit). install-sh is now able to install
multiple files in one run, so we could simplify our makefiles sometime.
install-sh also now has a -d option to create directories, so we don't need
mkinstalldirs anymore.
Use AC_PROG_MKDIR_P in configure.in, so we can use mkdir -p when available
instead of install-sh -d. For consistency with the rest of the world,
the corresponding make variable has been renamed from $(mkinstalldirs) to
$(MKDIR_P).
This switches the man page building process to use the DocBook XSL stylesheet
toolchain. The previous targets for Docbook2X are removed. configure has been
updated to look for the new tools. The Documentation appendix contains the
new build instructions. There are also a few isolated tweaks in the
documentation to improve places that came out strangely in the man pages.
update documentation accordingly. This is required in order to have support
for a reentrant scanner. I'm committing this bit separately in order to have
an easy reference if we later decide to make the minimum something different
(like 2.5.33).
This upgrades the configure infrastructure to the latest Autoconf version.
Some notable news are:
- The workaround for the broken fseeko() test is gone.
- Checking for unknown options is now provided by Autoconf itself.
- Fixes for Mac OS X
used to work as intended, but got broken some time ago (a quoted empty string
is not an empty string), and got broken some more by the changes to generate
ecpg's preproc.y automatically. Given all the unprotected uses of $(PERL)
elsewhere, it seems best to make use of the $(missing) script rather than
trying to ensure each such use is protected individually. Also fix various
bits of documentation that omitted to mention Perl as a requirement for
building from a CVS pull. Per a complaint from Robert Haas.
print foo --> print(foo)
string.join(...) --> ' '.join(...)
These changes are backward compatible.
The actual plpython module appears to need significant updates to support
Python 3.0, though. This change just relieves interested developers from
having to deal with Autoconf.
